Abstract:
Objective To investigate the distribution and antimicrobial resistance of the bacterial strains isolated from blood samples of inpatients in Longgang Hospital,Beijing University of Chinese Medicine.Methods The bacterial identification and antimicrobial susceptibility test results for the strains isolated from 2018 to 2022 were retrospectively analyzed.Results A total of 910 strains of bacteria were isolated from blood samples,of which 63.2％(575/910)were gram-negative bacteria and 36.8％(335/910)were gram-positive bacteria.Escherichia coli,coagulase-negative Staphylococcus,Klebsiella pneumoniae,Staphylococcus aureus,and Enterococcus spp.were the top 5 pathogens.In the past 5 years,no carbapenem-resistant strains of E.coli or K.pneumoniae were found in the blood samples of the inpatients.A.baumannii had a resistance rate of 11.8％to carbapenems.The prevalence of methicillin-resistant strains in S.aureus,S.epidermidis and other Staphylococcus species was 16.7％,75.0％and 55.5％,respectively.No vancomycin-or linezolid-resistant staphylococcual isolates were found.No strains of Enterococcus faecalis or Enterococcus faecium were found resistant to high concentrations of gentamicin,linezolid,or vancomycin.Conclusions The bacteria isolated from blood samples in Longgang Hospital were mainly gram-negative bacteria.Carbapenem-resistant strain was identified in the strains of A.baumannii.Bacterial resistance surveillance should be strengthened for the isolates from blood samples and other specimens from the site of infection.Antimicrobial agents should be used rationally to prevent the spread of drug-resistant bacteria.
